FIRE-ENGINE HEATER-CONNECTION.

SPECIPECATION forming part of Letters Patent No. 358,873, dated March 8,1887.

Application filed July 29, 1886. Serial No. 209,489. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH J. MEYRIoK, a

' citizen of the United States, residing at Louisville, in the county ofJefferson and State of Kentucky, have invented a certain new and usefulImprovement in Fire-Engine Heater- Oonnections; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theaccompanying drawings, forming part of this specification.

This myinvention relates to certain new and useful improvements inheater-connections for fireengines, consisting in a series of valvesarranged in chambers, four in number, inserted in the connecting-pipesbetween the engineboiler and heater in such manner as to produce aconstant circulation of water and steam between the heater andengine-boiler. Two of these chambers are attached to the engineboiler bymeans of pipes, with the pointed ends projecting in the rear of thefire-box near the floor, while the other two open ended chambers arepermanently secured to the floor on a line with the points of thefirstnamed chambers, and connected with the heater below by means ofpipes, one of which enters the heater near the bottom, while the otherenters near the top of both heater and boiler, and when necessary toconnect the engine with the heater it is backed until the pointedchambers enter the open ends of the stationary chambers near the floor,which operation opens the valves and forms adirectconnection between theboiler and heater,with the points of the chambers rendered water-tightby means of gum gaskets between the nuts on the ends and the points ofthe chambers.

The object of this my invention is to provide a series of devices forthe purpose of keeping the water in the boilers of steam fire-enginesconstantly up to the boiling point Without raising steam-pressure, inorder to facilitate the process of generating steam when the engine issuddenly called into requisition, and also to prevent freezing in coldweather.

I attain the above object by the mechanism illustrated in the drawings,in which- Figure 1 is a sectional view of the chambers, showing thearrangement of the valves therein. Fig. 2 is a sectional view of part ofthe end nuts, taken as indicated by X X, showing the openings around thevalve-guides. Fig. 3 is a sectional view of the main chamber, taken asindicated by Y, showing the valve-seat of the supply-valve and theopenings around it.

Similar letters refer to similar parts throughout the several views.

In the drawings, A represents the chambers attached to theengine-boiler, which are made of metal and in form as shown in thedrawings.

B is the end nut for attaching the connecting'pipes, and G is thevalve-stem guide, and D D are the openings around it.

E is a spiral spring around the stem F.

G is the main valve for shutting off water or steam when the engineisremoved for service, and H is a long stem extending out through thepoint of the chambers A, to answer as a trigger for opening up thewater-connection between the heater and boiler when the engine is backedup against the stationary chambers.

I I are the water-passage holes in the ends of the chambers A, and J isthe pipe which connects chambers A with engine-boiler near the bottom,and K is the pipe which connects the chamber A near the top of theboiler.

L L are the stationary val vc-chambers, which are made of metal and inform as shown in the drawings.

N N are the adjustable nuts for rendering the points of the chambers Awatertight when backed up against the chambers L by means of the gumring 0 between the parts.

1 P are also adjustable nuts, the upper parts of which answer as a guidefor the wings Q Q of the valve R It, which seats on thelower end of thenuts P, and S S are valves seated upon the upper side of thewater-supply openings T T, which is closed while the engine 'isin thehouse, thereby causing a free circulation of hot water and slight steambetween the boiler and heater through the openings V V; but as soon asit leaves the house again the valve S opens and valve It is closed bythe pressure of water and spring Z, thereby causing the water to flow inthrough the valve S down into the heater through the discharge-pipe W,which enters the heater near the top, while the pipe X enters it nearthe bottom.

Y is the stem of the valve It and S, which extends down into the guideM, with a spiral spring, Z, under it to assist the water in raising thevalve when the engine leaves, to admit i a fresh supply of water to theheater, which consists of a small cylinder-boiler placed in a verticalposition in the basement.

A is the connecting-pipe for the cold-water supply, which may be takenfrom the city hydrant or other source.

In order that others skilled in the art may understand its operation, itis only necessary, after the heater is set in position in the base mentand the chambers L L secured to the floor above and the chambers A Asecured in position in the rear of the engine, with pipes J and Kconnecting them with the boiler, and pipes W and X connecting them withthe heater below, as above described, to back the engine up until thepoints of the chambers A A enter the open ends of the chambers L L, whenthe nuts N N are screwed up against the gum rings 0 0 until awater-tightjoint is secured between the chambers, thereby forming adirect communication between the heater and engine-boiler, both at thetop and bottom of each, by which the hot water and slight steamgenerated in the heater below may circulate freely from one to theother.

Therefore, what I claim as my invention, and desire to secure by LettersPatent, in heaterconnections for fire-engincs, is

l. The chambers A A and nuts 13 B, pipes J and K, with valve-stem guidesG O, and water-openings D D around them, substantially as hereindescribed.

2. Combined with the chambers L L and A A, provided with extensionshaving openings 1 I and nuts B B, thevalves G G, having stems F F andspiral springs E E around them, with stems H H extending down throughthe ends of the chambers, to open the valve G-when the engine is backedup against the stationary chambers L, as above described.

3. In heater-connections for fire-engines, the chambers L L andsupply-openings T T, forming valve-seats U U in the interior, with thewater-openings V V around them, in combina tion with the pipe A, bywhich the chambers are connected, substantially as described, and forthe purpose set forth.

4. Combined with the chambers L L and supply-openings T T, the wingedvalves R and S, having seats U and stems Y, with guides M and spiralsprings Z, the nuts 1? P and N N, gum rings 0 O, and pipes N and X,substantially as described, and for the purpose set forth.
